Colorado Foothills (Denver) bird call mysteries!

[Spring Storm Mystery]

Hello — I've read Charlie Spencer's pinned post, so here we go!

I'm looking for identification and/or verification of five audio recordings I made on my iPhone today (May 27, 2019) in the Denver foothills. It is a mountainous region with coniferous and birch forest and I think lots of willow (not sure though). Wet season, late afternoon hike (3 – 4 pm), stormy and slightly rainy today, plenty of wind, dark clouds overhead with sun breaking through every so often. I managed to ID 10 or so species for eBird mainly by calls/songs only. However, these I'm not so sure about. I will try to upload the MP3s to this post.

Please disregard any and all broad-tailed hummingbirds calls/chirps and bells, those guys are like flies in summertime around this area!

Mystery 1 trill - Dark-eyed Junco — I'm pretty sure I've ID'd this one correctly, just looking for verification

Mystery 2 Trill - possibly junco — same bird?

Mystery 3 High Cheep - possibly cordilleran flycatcher — He's really loud! But I'm not sure of my ID.

Mystery 4 Trill-like - possibly junco — later in the day

Mystery 5 two flute — This one is impossible to hear. At the very end of my day, I suddenly heard a two-note flute ("ooop ooop"), same pitch, and I matched the pitch with the very start of a Bewick's wren call (total coincidence, and that bird is not here in my state). I tried to find a youtube video of its call so I could edit a fake version of the call, but turns out that's more difficult to find that little piece of sound. Audubon and Merlin ID apps didn't help me. I swear I've heard him before. Way off in the distance, you may hear the two "hoots" but it's a fluted call, not owls.

 

Any help would be immensely appreciated. Thank you!!

Yeah, that was probably your first mistake.

Should I suppose audio IDing isn't quite as popular as visual ID'ing? :)

It's more a case of there aren't as many people capable of ID'ing calls accurate.

The best way for me to learn bird songs is if I can see the bird while it's singing. This seems to lock it in my brain. But it only works on birds that sing. I see boatloads of Song Sparrows from October to April but they rarely sing in this market (GA). It was only fairly recently that I learned that Song sparrows even have a song. Migrating passerines in general have little to say. They're busy forging for fuel for the next leg of their journey. I see a few juncos in the winter but I don't hear anything out of them.

Still, some birders are quite accomplished at identifying bird songs, even when a recording has multiple birds and other background noises. So here's another bump in the hope that someone can help.
